TMTOWTDI, but the common way to do this is to add the long-running job to a
job queue, and then redirect the user to a page that periodically checks if
the job is done by using JavaScript requests.

If you don't have a job queue and don't want to add one just for this, you
could use a cleanup handler to run the slow stuff after disconnecting:
http://perl.apache.org/docs/2.0/user/handlers/http.html#PerlCleanupHandler

That will tie up a mod_perl process though, so it's not a good way to go
for large sites.
